fF ig. 6 is a planvi/ew Villustrating a slightlyvmodified formy of therotaryv member and the surface by means 'of which the bricks are' amodiiedconstruct'ion of supporting' means therefor. 'i Y As'hereshown lis a suitable lsupporting frame-work in a. portion'of'wh-ich isrotatably 70 mounted in bearings a horizontal shaft 2Q According to thepresent invention-there" 1s .provided afzrotary member"comprising aboss?) fixedv upou'fthe'lsliaft 2 `and from lwhich boss :radiate-atfsuitable peripheral intervals 75 one or more arms, as 4, 5,6 and 7each pro-V vidting surfaces uponwhich bricks as 84 may Coeoperating withthe said rotaryV member is aloading surface horizontally disposed," orinclined at a 'slight angle, and extending to wards the said rotarymember in a direction at' right angles with the saidf axis 2,' to apositionpast which each ofthe said arms, 4, 5, gand 7 in turn risesduring the rotary movement of the said rotarymember.

As hereshovvnv in Figs. l, 2, 4 andk 5 the said loading surface consistsof a-stationary table 9 having a slot or opening l0 (Figs. 4' and- 5)vthroughjwhich the arms of the rotary member rise, a push-blockfll beingin this case provided and operated with a reciprocal movement'over thetable 9 to forward the bricks to the Said arme l f l o5 I nthe preferredform of the construction, as here shown, the portion 'of the tablej 9over which the push-block l1 moves is formed with adlongitudinal fslot57 in which a dependent tonguepiece 58 upon the push-block 10c isslidably received, thereby'to guide, or assist in guiding suchpush-block in its said reciprocal movements.

In a. modified form shown in Fig. 6 however, in lieu of the stationarytable 9 and push-block 11, the loading surface consists of a travellingconveyor-belt 12 and in this form also the arms 4, 5, 6 and 7, instead.of being solid as in the previously described form, are bifurcated topermit of the belt 12 running in the space or interval between their twobranches or lingers.

It will be understood however that these two forms of the loadingsurface and the arms are given merely by way of example and that thereis no reason why each of the said arms should not be bifurcated ordivided into two or more branches or lingers to co-operate with acorrespondingly shaped stationary loading table, or alternatively theloading surface might consist of a parallel pair of conveyor-beltsco-operating with solid arms rising therebetween.

Y Again if so desired the said loading surface may be arranged todeliver the bricks to the arm in a direction parallel with the axis 2.

The present invention is therefore to be construed as including withinits scope each and all of such modifications.

In all cases the arrangement is such that a plurality of bricks havingbeen forwarded along the loading surface to the required,

position within range of the arms, will be received and lifted from suchsurface by the arms as they rise therepast, as here illustrated in thecase of the arm 4 Figs. 4, 5

and 6. Y

As the rotation continues the loaded arm in approaching its verticalposition, will placeA its bricks in stacked formation oneY above theother, as here shown in the case of the arm, Figs. 4 and 5.

At this stage the bricks will be removed vfrom the arm by the Operationof an ejecting device, which conveniently takes the form of a push-block13 operating with a reciprocal movement parallel with the axis 2.

v In order to steady the bricks on reaching their said ejectingposition, there will preferably be provided a stationary verticalsurface orrmember 56 with which such bricks will come in contact, thesaid surface or member being so formed as to offer no obstruction to thesubsequent passing of the arm. Thus for example the said member may takethe form here shownA comprising a pair of uprights which serve to engagethe bricks while the spacel or opening between such up-l rights allowsof the arm passing therethrough when the movement of the rotary memberis resumed after the ejection of the bricks has taken place. Y

The bricks, when ejected from the rotary member, are directed, as bymeans of a chute 14 onto a conveyor 15 ranged alongside the rotarymember'toreceaivesuchbricks in rows extending transversely of suchconveyor.

The said conveyor may consist of a trolley or barrow as here shownarranged to run upon a rail track 16 Fig. 1, extending at right angleswith the direction of the said discharge and such conveyor` or thebricks supported thereon, will be subjected to forward impulses by meansactuated by the mechanism and whereby, as each row of bricks iscompleted,-the conveyor will be moved along the track for a suflicientdistance to place it in the required position to receive the nextsucceeding roW and so on until the load is completed. In one preferredform of the construction,

as here shown, this movement of the eonveyor is attained by theemployment of a push-- block 17 adapted to perform a reciprocal orvibratory motionabove the conveyorv in a direction parallel with thetrack 16 the `arrangement being such that as each row is completed thesaid push-block in performing its said movement will comein contact withthe last portion` of the rowand thus serve to move the conveyor thenecessary distance to receive the next row. y In order to prevent theconveyor, when so actuated, from over-running Athe required distance,provision is preferably vmadefforj causing such conveyor to .becomelocked `in each of its Vsaid loading positions. A f This locking mayconveniently be attained as here shown bythe provision of a spring 18stationarily'mounted at the. side ofthe track, such spring beingprovided in its free end with a pin 19 engageablewith Yany one of aseries of holes 20 provided at the re-t quired. intervals lengthwisealong theside o4 the conveyor, the arrangement being such that, as thevehicle moves forward, thenat-l ural tendency of the spring will causethe pin toventer the first of the holes 20 with which it comes intoregister.` A

` As here shown, in order to disengage thev pin from the hole beforeeach forward move-i ment of the vehicle takes place, the said free endoffthe spring lever 18 is provided also with a' contact-piece 21 adaptedto be engaged by end of eachv row of bricks as the latter comes intoposition upon such conveyor thereby forcing such spring outwardslightly` and so disengaging the pin.

In the vpreferred form ofthe construction also the deck of the conveyor,or a removable pallet supported thereon, is provided at theV requiredintervals with'transversely disposed ridges or separators 22 upstandingslightly above the surface of such deck or palletto guidev the rows ofbricks into place thereon in the'desired open formation. Y

When the-bricks lie side-by-side in v,this position1 the sliding plate46 will be moved by the laction-ofthe rock leverv 40 to` present`itsnotch 47 tothetoothed wheel 45, thereby which one of its said arms4,. 5,.6 or..7aS thef'a case may be, will rise from an approximatelyhorizontal position lifting the said bricks from the loading surface andobtain an approximately vertical position thereby stacking such bricksone upon the other.

In this position the rotary member will pause .and become locked by theaction of the rock lever 40 in moving the sliding plate 46 so as tocarry the notch i7 out of register with Lthe toothed Wheel 45 afterwhich the push block 18 will advance to engage the end of the stack ofbricks and push the sameclear of the arm into the chute lil. e The aboveexplained cycle of operations will' then be vrepeated so as to similarlyload bricks onto the next succeeding arm and discharge them in stackedform into the chute where they will cause those previously delivered tobe pushed onto the conveyor.

Upon the completion of the loading of each row oflbricks upon Ytheconveyor the end bricks of such row will engage the contactpiece '21thereby disengaging the pin 19 from the hole 20 which it previouslyoccupied thereby unlocking the conveyor, while the end stack ofbricksupon attaining their position upon the conveyor will also beengaged by the push block 17, as the latter performs its said reciprocalmovement, thereby causing the conveyor to be advanced for the correctdistance to receive'the next row whereupon the pin 19 will engage withthe next succeeding hole and so lock such conveyor in position andprevent it' from overrunniiig.
